    libpayload: New CBFS to support multiple firmware media sources.
    
    Upgrade CBFS in libpayload to use new media-based implementation from coreboot
    ( http://review.coreboot.org/#/c/2182/ ).
    
    Old CBFS functions (cbfs_find, cbfs_find_file, get_cbfs_header) are still
    supported, although the recommended way is to use new CBFS API.
    
    To migrate your existing x86 payload source:
    	- Change cbfs_find to cbfs_get_file
    	- Change cbfs_find_file to cbfs_get_file_content
    	- Prefix every CBFS call with a CBFS_DEFAULT_MEDIA argument.
    
    Ex, char *jpeg_data = cbfs_find_file("splash.jpg", CBFS_TYPE_BOOTSPLASH);
     => char *jpeg_data = cbfs_get_file_content(
    		CBFS_DEFAULT_MEDIA, "splash.jpg", CBFS_TYPE_BOOTSPLASH);
    
    The legacy setup_cbfs_from_{ram,flash} is also supported, although the better
    equivalent is to make a new media instance:
    	struct cbfs_media ram_media;
    	init_cbfs_ram_media(&ram_media, start, size);
    	char *data = cbfs_get_file_content(&ram_media, "myfile", my_type);
    
    Verified by being successfully linked with filo.
